Six custom bulletproof vests for police dogs were donated to the San Francisco Police Department's Canine Unit Wednesday through a donation from the "Cover Your K-9" program.

The unit also received K-9 stat packs, which are about the size of a wallet and equipped with hemostatic pads, which help to stop bleeding, and other emergency supplies for a K-9 handler to have on hand to protect their canine partners in the line of duty.

Several San Francisco police dogs with their human counterparts modeled the vests at an event on Treasure Island Wednesday morning and the packs were also on view.

The vests and other supplies are provided through a program run by the Woodside-based non-profit the Police and Working K-9 Foundation, which provides support and resources for canine units at law enforcement agencies throughout California.

The life-saving packs cost about $75 each and the San Francisco police donations were funded by the foundation's 2013 fundraisers at Pet Food Express stores.

According to fundraiser organizers, last year more than $121,000 was collected at California stores.

Pet Food Express stores throughout the Bay Area are holding fundraisers this weekend for the "Cover Your K-9" program to supply more tools and equipment for more police dogs and handlers.

At participating stores, including the Pet Food Express on Market Street in San Francisco and more than 25 other Bay Area locations, all proceeds from dog washing sessions on Saturday and Sunday will go to the program.

Dog washes are $15 per token and tokens for future washes purchased during the fundraising weekend will also give money directly to the K-9 program.

K-9 units and their partners from different police agencies will be stopping by many of the participating stores at various times during the fundraiser.

A complete schedule and location listing is available at the Pet Food Express website.
